OpenGL Performer provides the advanced features and innovative
techniques that enable you to achieve peak performance and make optimal
use of system capabilities and sophisticated 3D graphics features. It
gives you the capability to scale easily to multiple processors and
multiple graphics pipelines, deploy to a wide range of systems and
price points, and be ready-made for the graphics systems of today and
the future.

OpenGL Performer is built atop the industry standard OpenGL®
graphics library and, includes both ANSI C and C++ bindings. It forms
the foundation of a powerful suite of tools and features for creating
applications on all Silicon Graphics® systems running IRIX® 6.5 or

systems with Microsoft® Windows® 2000 or Windows® XP.

OpenGL Performer is an integral part of the SGI® Onyx® Series
visualization systems and visual workstation simulation solutions from
SGI and, in particular, provides interfaces to the advanced features of
InfiniteReality® and UltimateVision™ class graphics. OpenGL Performer
is the flexible, intuitive, toolkit-based solution for developers who
